Move over, pipsqueak.  
The stock intercooler has an inferiority complex. No wonder it's smaller than Techni-Cooler in every aspect: boost tubes. core area, inlet/outlet, even the end tanks. Most competitors use poorly designed sheet metal end tanks and provide inadequate flow volume.

Banks cranks up the volume.  
Banks improves airflow into and out of the intercooler with big mandrel-bent 3 inch boost tubes. Large, rugged, high-efficiency cast end tanks that won't' rupture under high-boost conditions. A huge inlet and outlet. And a 25% larger core area with a whopping  34% improvement in volume

The king of cool.  
Removing restrictions and improving airflow lowers boost air temps. This increases the density and oxygen content of air entering the engine, which amplifies power, lowers exhaust gas temps (EGTs) and improves fuel economy. When EGTs are tamed, the tuner doesn't need to limit fuel delivery. So you get higher continuous, useable power and more power at any EGT. Very cool!

Everything about Banks Intercooler is bigger, it doesn't get any cooler than Banks Intercooler.
